Operation Antarctica takes place after the events of Cronus Frontier. The mission tasks the player with investigating a blackout at the Antarctic Research Facility (ARF), Earth, which has lasted over 72 hours. The player must destroy or bypass each sector to gain deeper access into the facility. Expecting the worst, the player fights their way into the ARF to find autonomous operators have massacred most of the ARF's personnel. The player rescues survivors, locates an unidentified power signature, then discovers an ancient alien refinery beneath the facility. The player is instructed to destroy the entire facility because this refinery has begun independently producing auto-ops of unknown design. The player overloads the "nuclear heart" to obliterate the ARF and escapes to the surface.
